I was interested in the tyres too, however was put off posting due to the moderator comment. It seems a taboo subject to point out that some people ask for an amount which reflects retail prices. A good example of this is
ebay, once it was a good place to grab a bargain but if you watch a number of auctions many items go for around or over prices that you can buy for brand new and delivered from e-tailers.
Wiggle have them on for £12.76. Riding on them (as in they are not new) has now made them 'used'. I think that the lack of interest has shown that the price could be revised is all I would add.
Good luck on the sale.
